CLOSURE FOR RECEPTACLES.

Specification of Letters Patent.

Patented Ma 21, 1918.

Application filed October 12, 1915. Serial No. 55,423.

To all whom it may concern:

Be it known that I, HARRY L. HUosoN, a citizen of the United-States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Closures for Beceptacles, of which the following is a specification.

The object of this invention is to provide a receptacle having a tubular member, which may be closed by a cap which is automatically locked in position on the tubular member when pressed thereon.

Another object is to provide a means for releasing the cap from the tubular member.

A still further object is to provide certain improvements in the form, construction and arrangement of the several parts whereby the above mentioned and other objects may be effectively carried out.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 represents in side elevation a portion of a receptacle having a tubular member and a cap thereon,

Fig. 2 is a vertlcal central section through the same,

Fig. 3 is a vertical central section of a pogtion of a modified form of receptacle, an

Fig. 4 is a vertical central section of a neck of a bottle with the cap applied thereto.

The body portion of the receptacle is denoted by 1 and is provided with a tubular member 2 which is adapted to be closed by a cap 3. The tubular member may be formed integral with the body, as shown, or it may be secured thereto in any well known and approved manner. The upper edge of the tubular member 2 is extended outwardly and downwardly, as shown at 4, the edge forming an outer annular rim at the mouth of the member.

The cap 3 has a depending flange 5 which is arranged to snugly embrace the outwardly and downwardly extended upperedge of the tubular member. The flange 5 is provided with means for securing the cap to the tubular member, which means is herein shown as consisting of one or more up- 'wardly directed spring tongues 6 pressed inwardly from the flange at the proper point to snap inwardly under the outwardly and downwardly extended edge 4 of the tubular member 2, when the cap 3 is pressed into its position.

A gasket 7 of rubber or other suitable material, is inserted between the tubular member and cap to take up any inequalities in the metal and to make a tight closure. A band 8 is fitted to slide freely upon the tubular member between the body and the edge 4, and in position to pass between the flange 5 and the tubular member, so that the edge 9 of the band may be forced against the tongues and the tongues pressed outwardly clear. of the downwardly extended edge 4, in which position the cap is free to be removed from the tubular member.

The band 8 may be split, as shown at 10, to permit it to be placed in position after the outwardly and downwardly extended edge 4 has been formed on the tubular member, but this is not an essential feature of my invention. The band is also provided with a flange 11 for reinforcing and stifiening it.

In the modified form, shown in Fig. 3, the band has been omitted.

In the form shown in Fig. 4, the tubular member 12 is made of glass or porcelain, and has formed thereon an outwardly extended rim 13, which is adapted to be engaged by the spring tongues 14 of the cap 15. A disk of cork 16 or other material, is interposed between the cap and the mouth of the tubular member for making a tight closure and holding the cap firmly thereon.

It is evident that slight changes might be resorted to in the form, construction and arrangement of the parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein shown and described, but

What I claim is 1. A receptacle comprising a tubular member having an outwardly extended upper edge, a cap fitted to cover the tubular member, said cap having a depending flange provided with one or more upwardly directed spring tongues pressed inwardly therefrom arranged to snap inwardly under the outwardly extended upper edge of said tubular member for locking the cap against removal and means having walls parallel with and adapted to slide on the tubular member and within the flange of the cap to engage the tongue or. tongues and force them outwardly to allow the cap to be removed from the member.

2. A receptacle comprising" a tubular member having an outwardly extended upper edge, a cap fitted to cover the tubular member, said cap having a depending flange provided with one or more upwardly directed spring tongues pressed inwardly therefrom'arranged to snap inwardly under the outwardly extended upper edge of said tubular member for locking the cap against removal and a band having walls parallel with and adapted to slide on the tubular member and within the flange of the cap to engage the tongue or tongues and force them outwardly to allow the cap to be removed from the member.

3. A receptacle comprising a tubular member having an outwardly extended up per edge, a cap fitted to cover the tubular member, said cap having a depending flange provided with one or more upwardly directed spring tongues pressed inwardly therefrom arranged to snap inwardly under the outwardly extended upper edge of said tubular member for locking the cap against removal, and a split band adapted to be moved upwardly between the tubular memher and the flange 0f the cap forforcing the tongue or tongues outwardly to release the cap from the member.

In testimony, that I claim the foregoing as my invention, I have signed my name, this 4th day of October, 1915.

HARRY L. HUDSON.
